TCMT110208-MM4 WSM20S turning insert (triangle 60°, for rostfreier Stahl and superalloys) — Walter Tools

The TCMT110208-MM4 WSM20S is a triangular, coated carbide turning insert designed for heavy-duty applications on rostfreier Stahl and heat-resistant superalloys, offering stable cutting performance under high thermal loads.

• Tiger·tec Silver coating for thermal stability
• Optimised MM4 chipbreaker for secure chip control
• Triangle 60° shape; 0.8 mm nose radius
• Suitable for rostfreier Stahl and high-temperature alloys

Consistent productivity through thermal-stable grade technology

The combination of the Tiger·tec Silver coating and the WSM20S grade produces controlled wear behaviour and improved heat resistance compared with uncoated alternatives. Coated carbide inserts protect the hard substrate against high cutting temperatures and abrasive wear; this means fewer tool changes and a lower cost per component in serial production. For machining rostfreier Stahl, which tends to generate heat and form built-up edges, the coated surface supports stable chip formation and reduces the risk of premature edge breakdown. The result is a measurable improvement in process stability and repeatability across batches.

Geometry engineered to prevent downtime and improve surface finish

A well-matched tool geometry is essential for predictable machining. The MM4 chipbreaker is tuned to guide and fragment chips reliably even under heavy cutting conditions, reducing interruptions from long swarf and the incidence of built-up edge. The triangle 60° insert form provides three usable cutting edges per indexation, while the 0.8 mm nose radius balances strength and achievable surface quality. The 7° clearance helps to avoid rubbing while keeping cutting forces within machine capabilities. Together, these features minimise reworking and extend productive runtime without compromising component finish.

Application focus: where this insert adds the most value

This insert is specified for work on rostfreier Stahl (ISO group M) and on demanding superalloys and titanium-type materials (ISO group S), as indicated by its material suitability codes S / M. It is particularly advantageous where heat generation and workpiece toughness place higher demands on the cutting edge. In practice, the insert supports stable turning in roughing and semi-finishing operations when used with appropriate cutting parameters and secure clamping. If additional cutting data or recommendations for toolholder geometry are required, Metav Werkzeuge’s technical team is available to provide machining guidance and suggested starting parameters.
